What is the actual hostname?
You can work around this by partially qualifying the hostname, too. For example,
something like "rg-218.lab" would be accepted. The heuristics for the check in
the javascript are about as basic as possible: if you don't enter an IP address,
it just checks for at least one dot in the hostname.
